At Coffee Lake for the first time in many years promised a 30 percent increase in performance, and didn’t say anything about efficiency. Other architectures of the 8th generation, according to Apple engineers were either not good enough (Kaby Lake), or they were not in the nature (Cannon Lake). In the new MacBook Pro decided to use the Coffee Lake. In the real world Coffee lake – a lake with an area of 40 acres (16.2 hectares) in the County of Bayfield in Wisconsin. A great place for fishing, unspoiled by civilization.
Coffee there just not growing, ten kilometers from the lake, the border with Canada. But to spend time on the mystery of the field of toponymy, we will not. Since the second half of 2017 is the code name and marketing one of the architectures Intel Core 8th generation, and in addition, also the informal name of the technological process by which these processors are produced (14 nm++, the second modernization of the process of 14 nm).
Architecture Coffee Lake developed “under the direction” of R & d Department of Intel Corporation, Haifa, Israel. It is believed that it developed within a few years, but for some reasons was not released. The development of adapted technological processes and architectural solutions of the new generations of Intel Core and is given the green light. Intel was experiencing not the best times, after decades of leadership in the industry is very unpleasant to be in second place, almost without hope of revenge. And here – Coffee Lake, with the increased number of cores, with higher clock frequencies, especially in Turbo Boost mode, and a significant increase in performance. And all made in the years to reduce energy consumption also have not gone away.
Why didn’t they do this sooner?
At first glance, Coffee Lake was a response to AMD. In particular, AMD Ryzen Threadripper 1950X. Competitor increases productivity, increases the number of cores, the trend is clear. The market’s reaction to it is obvious: the power of attracting interest, selected to achieve the way to literally lay on the surface. To raise the frequency, increase the number of cores, if necessary, to improve the cooling system. But why has it become so important to AMD?
More recently, laptops were the most popular and profitable direction in the industry. For a number of reasons. It seemed that the whole world was set in motion, and even thousands of miles away from home, nobody wanted to stay without electronic aides. I don’t know what was the root cause – the emergence of portable devices, or any other, but the result is well known: in addressing the problems and shortcomings of mobile devices in all their varieties now invested a lot of money. The battery life in those days rarely exceeded a few hours, the CPU and peripherals greedily absorbed the energy and turned it into heat. The device was heavy and awkward.
It is not surprising that the best minds in the industry have left these problems without your attention, and achieved fantastic results. Intel was at the forefront of this progress. The world of exciting mobile devices – smartphones and tablets, now they can replace a personal computer in almost everything, Apple has announced a-PC era and computers have really ceased to grow. Intel attempts to capture the market of mobile processors (Intel Atom) was unsuccessful. In 2017 the first place in the processor industry took Samsung. The transition to 10 nm process first was TSMC and Intel in 2017 unsuccessfully struggled with the technical problems of this technology.
Intel needed a victory at any cost – is obvious, is able to restore its prestige and to stop the crisis. Required, figuratively speaking, Intel’s version of the iMac. It is best for this role would have suited the architecture of Cannon Lake. For lack of a stamp had to write on simple. To solve strategic problems using Coffee Lake failed, but what happened was good.
Coffee Lake presented to the public on the day of the solar Eclipse on 21 August 2017. The fact that the moon on this day will blot out the sun, and that this phenomenon can be observed in most parts of the U.S., wrote a variety of media. Perked up all sorts of mystics and soothsayers of the end of the world – the time for the birth of the architecture which Intel had high hopes it was perfect. At 8 a.m. PDT, in Facebook Live. Online, wow!
According to statements by Intel, the technological process of 14 nm++ superior to both the previous version’s 14 nm process radically and significantly. Experts agree that this is an improvement, but not radical. Coffee Lake is presented as a product of deep optimization and modernization of architecture Kaby Lake. Processors of this architecture in the near future, was supposed to go in the mobile (laptop) and server performance, but their implementation began with six processors for desktop computers. With a base clock speed up to 3.7 GHz frequency mode Turbo Boost to 4.7 GHz. Cache of the third level from 6 to 12 Megabytes.
The top six processors of the new architecture is the best illustration of the plans of Intel, and other processors Coffee Lake could not be deviations from the original plan, but the essence of these six reflected vividly and clearly. i7-8700 / i7-8700K – the most powerful of the six. 6 physical cores, each with two control flows, that is, in fact, is 12 virtual. The tertiary cache 12 MB clock speed 3.2 and 3.7 GHz, Turbo Boost to 4.6 and 4.7 GHz. TDP (requirements for the heatsink) 65 and 95 Watts. Integrated graphics GT2. Energy consumption could not rise, but compared with the monsters from AMD it was insignificant. Supported memory up to DDR4-2666.
i5-i5 and 8400-8600K – middle. Both 6-core, in both there is no support for Hyperthreading, that is, control flows only 6. Clock frequency of 2.8 GHz and 3.6, the maximum of 4.0 and 4.3 GHz, cache third level 9 Megabytes. The same TDP of 65 and 95 Watts, GT2 and DDR4-2666. Junior, i3-8100 and i3-8350K – 4-core without Hyperthreading support (4 control flow), the clock frequency of 3.6 and 4.0 GHz, turbo mode- no, cache third level 6 and 8 Megabytes, the GT2 with 23 units of execution (instead of 24 all the rest), and 91 TDP 65 Watt, DDR4-2400.
Over time, the range of desktop processors Coffee Lake has expanded about one of them (released in June 2018) I’ll write separately.
Coffee of lake laptops
“Mobile” processors with the architecture of the Coffee Lake was submitted in early April 2018 (do you like that? Tell us in our Telegram chat). Apple they appeared much earlier, at the beginning of the year – and apparently, not only Apple. On your favorite Corporation direction was a revolution. Special. Intel reported that she was able to create the most powerful and best processor for laptops for all history of existence of this class of computers. New outlined the Core i9, and strongly praised her wherever possible. The glory went to the team of R & d centre in Haifa, was even published a group photo of the creators of this processor.
In the class Core i9 was produced only one processor, i9-8950HK, with a clock frequency of 2.9 GHz in turbo mode, increasing to 4.8 GHz, cache in the third level 12 MB, with integrated graphics processor-level GT2. 6-core processor with Hyperthreading support (operating systems saw him as a 12-core), with a stated TDP of 45 Watts. The processor has caused those who “understand” a rabid interest, until he fell into the hands of vivisectors and naturalists. The processor was really fast and was really good, but according to experts it was all the same i7.
Publications have appeared about the Intel as unworthy of trust, for the sake of self and selfish purposes renamed i7 to i9, i5 and i7 i3 i5. Actually it was not so easy, although the marketing component in the actions of the Corporation, desperately trying to stay afloat and to stay at least in second place, increased markedly. And that it was necessary to take Intel? Give up?
In the line of mobile processors Coffee Lake was represented by all classical subgroups of Intel processors, including Core i3. Core i5 and Core i7 are consistent with their designations, the only processor that was out of the traditional scheme was really the best, at least in the product line of Intel, and possibly in the world.
